This is a weakly documented and hence suspect occurrence, and not to be confused with the BV or Muncho Lake Barite developed prospect (094N 002) 9 kilometres to the north. The original 1944 reference simply states that veins of fluorite and barite are reported to be relatively common in the limestone south and east of Muncho Lake, presumably near the Alaska Highway (Geological Survey of Canada Paper 44-28; Minister of Mines Annual Report 1960, page 134). Stratabound and vein barite is indeed present at several localities in the region, mainly in Devonian carbonate rocks, especially the Middle Devonian Dunedin Formation; minor fluorite is present in some of them. It is possible that the reference refers to occurrences a considerable distance from Muncho Lake itself.

The Dunedin Formation outcrops within a northwest-trending belt about 10 kilometres east of Muncho Lake, but is apparently not represented near the highway around Muncho Lake, where Silurian and other Devonian carbonate units occur (Geological Survey of Canada Map 1343A, Memoir 373). Given the uncertainties of location and stratigraphic host rock, the occurrence is somewhat arbitrarily located, namely next to the highway at the southeastern corner of Muncho Lake, which is underlain by the Silurian Nonda Formation.
